This map is an approximation of precinct-level results. Hover over the various voting blocs to see how each area voted. You can also search by ZIP code and choose your polling place from the list.


Why do the precinct borders look different from the ones I’ve seen in the past?

What we’re showing on this map isn’t “exactly” precinct borders because the precinct maps have not yet been drawn by state election officials since redistricting was completed in April.

The Baltimore Banner reached out to both the Maryland Board of Elections and the Maryland Department of Planning, two agencies tasked with administering elections in the state. The department of planning said it is in the process of compiling precinct borders, but they have not yet turned it into a state-level precinct map.

How did The Baltimore Banner compile its maps?

We are using a series of computational techniques to estimate something close to the correct borders.

We created geographic voting blocs based on polling places. The area inside each bloc is closer to that polling place than any other. Then we assigned the votes cast at that polling place into each geographic bloc to visualize the results. This approximation of precincts is the most accurate we can get with the available data.

How could it be different from a precinct map?

Voters aren’t always assigned to their closest precinct; however, it is largely true that they are. This is least true for city voters whose closest polling place is in the county.

What votes are included in the map?

The map reflects early voting and election day voting. It will be updated later with mail-in ballot votes.

So why did we do this?

It’s unclear when the department of planning will release the digitally-drawn precinct boundaries (or shapefiles). We want readers to be able to see how their neighborhoods voted. Marilyn Mosby, for example, largely won voting blocs in what is traditionally known as the “black butterfly.”

The value of the information, combined with the high degree of accuracy, outweighs potential minor inconsistencies in the data. When the state releases the precinct maps, we will will update our maps.
